Not exactly.

A query variable that isn't being used.. well.. isn't being used. You
have to actually attempt to use query variables to know they're there.

In the code, calling http://example.com/?abc=123 will set the
$_GET['abc'] = '123', but if I'm not looking at the $_GET['abc']
variable, then it doesn't make any difference what it is.

It's not stripping off the query variable, it's just looking for the
query variables that it's looking for, and "fedd", "apples", and "abc"
aren't in the list of variables being used.
